Answer:

see explanation

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 = 6 parts

Divide 180° ( sum of angles in a triangle ) by 6

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

The angles in the triangle are 30°, 60°, 90°

Then the triangle is right angled

Answer:

Step-by-step explanation:

Let missing angles be [tex]x[/tex], [tex]2x[/tex].

As the triangle is right-angled triangle.

[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]

[tex]3x = {180}^{o} - {90}^{o} [/tex]

[tex]3x = {90}^{o} [/tex]

[tex]x = {30}^{o} [/tex]

[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]

Answer: 3 054 in^2

Step-by-step explanation:

Sphere volume formula = 4/3 pi r^3

So... 4/3 pi 9^3

= 3 053.63 in^2

The volume of pyramid A is 20 cubic inches.

Given that:

Height of pyramid of A and B are 6 and 15 inches, respectively.

Since square pyramid A and square pyramid B are similar, their corresponding sides are proportional.

Let the volume of pyramid A be V and the scale factor between the two pyramids be k.

The volume of a pyramid is given by V = (1/3) × base area × height.

Since the base of pyramid B is k times the base of pyramid A, and the height of pyramid B is also k times the height of pyramid A, we can set up the following relationship:

V(B) = k³ × V(A)

Given that the height of pyramid A is 6 inches and the height of pyramid B is 15 inches, we can calculate the scale factor k as follows:

k = height of B / height of A = 15 / 6 = 2.5

Now, we know the scale factor k, and we are given the volume of pyramid B as 312.5 cubic inches. We can find the volume of pyramid A:

V(B) = k³ × V(A)

312.5 = 2.5³ × V(A)

312.5 = 15.625 × V(A)

Now, solve for V(A):

V(A) = 312.5 / 15.625

V(A) = 20

The volume of pyramid A is 20 cubic inches.

Answer:

To the nearest tenth of a percent, the approximate equivalent monthly depreciation rate is 1.0%

Step-by-step explanation:

From the question, we have a per annum decrease of 12.4%

what this mean is that, yearly, we expect a decrease of 12.4%

To get the monthly decrease value, we have to divide this given value by the number of months in a year which is 12

Thus, we have it that;

12.4%/12

= 1.0%

To the nearest tenth, the monthly decrease percentage is 1.0%

Answer:

y = 3x + 9

Step-by-step explanation:

y = 3x + 6

Parallel slope = 3

(-2, 3)

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 3(x + 2)

y - 3 = 3x + 6

y = 3x + 9

Answer:

please mark me

length of the diagonal is 14 feet good luck

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The shortest side is the side opposite the smallest angle, the longest side is opposite the largest angle.

First find the measure of the angles in the triangle.

The sum of the 3 angles = 180° then

5x + 40 + 10x + 7x + 8 = 180

22x + 48 = 180 ( subtract 48 from both sides )

22x = 132 ( divide both sides by 22 )

x = 6

Then

∠ A = 7x + 8 = 7(6) + 8 = 42 + 8 = 50°

∠ B = 5x + 40 = 5(6) + 40 = 30 + 40 = 70°

∠ C = 10x = 10(6) = 60°

The shortest side is opposite ∠ A , that is BC

The longest side is opposite ∠ B , that is AC

The sides in order from shortest to longest are

BC, AB, AC → D

A

Answer:

Mean - 89

Median - 90.5

Mode - 89 or 92

Q1 - 84.5

Q3 - 96.5

IQR - 12

Step-by-step explanation:

A mean is an average. Just add all numbers then divide by how many numbers there are.

A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.

A mode is the number that appears most often. Count how many of each number there is.

Q1 is the middle of the lower half of the data.

Q3 is the middle of the upper half of the data.

IQR is the difference between Q3 and Q1. (subtract)
